IMPROVEMENT IN PLANlNG MACHlNE$.

Specification forming part of Letters Patent No. 149,128, dated March31, 1 874 application filed June 28, 1873.

To all whom it may concern:

Be it known that I, O. G. HOWES, of Fort Ann, county of Washington,State of New York, have invented a new and useful Improvement inPlaning-Machines; and I do hereby declare that the following is a fulland exact description thereof, reference being had to the accompanyingdrawings making a part of this specification.

Figure 1 is a side elevation of a planingmachine. Fig. 2 is a plan ofthe same. Fig. 3 is a cross-section in a plane indicated by line an acof Fig. 2.

Similar letters refer to corresponding parts in all of the figures.

The nature of my invention consists in a swinging cutter-head capable ofbeing adjusted to and secured at any angle departing from a right anglethat may be desired.

I employ a cast-iron frame, A, similar to those ordinarily used. To thesides of the frame A I cast projections D d, as seen in Fig. 2. In theprojection D I make an elongated slot, E, the length of which isdetermined by the swing of the cutter-head and bar upon which it rests,and being described upon a radius the length of which is the distancebetween the centers of the two bolt-heads a F, thus the bolt-head abeing the center of the arc of the circle described at E. The bolt apasses through the projection at, so as to allow of a nut being screwedupon it. 0 represents a bar of iron, upon which the cutter-head issecured by appropriate standards and boxes, and operated as in ordinarymachines. The bar 0 is secured at one end by the bolt (1, and at theother end by the bolt F, which passes through the slot E, and is held toits place by turning a nut 011 the under side of the projection D, thussecuring the cutter-head at any angle required. I I are two feed-rolls.e is a pulley for driving the saw I).

dressed. When the cutters are at an angle of forty-five degrees they arecutting diagonally across the grain of the wood, that being more of adrawing or shearing out than is otherwise obtained by placing thecutters at any other angle between a right angle and an angle offorty-five degrees to the bed of the machine or surface to be dressed;but for particular materials or purposes some other angle may bepreferred. 1

This machine is adapted to planing doors, although it can be used forall purposes that other planing-machines are used for.

The saw b is used for cutting the edges and inequalities from the edgesof the doors as they pass through the machine.

What I desire to secure by Letters Patent 1s- The cutter-head B,attached to the swinging bed, as shown and described,in combination withthe frame A of a planing-machine, when all the parts are constructed andoperate in the manner specified.
